HORSESHE.

SPECIFICATION forming part of Letters Patent No. 270,784, dated January 16, 1883.

Application filed November 22, 1882.

' To all whom it may concern:

Be it known that I, FRIEDRICH ALBERT GAUER, of Hamburg, Germany, have invented a new and useful Improvement in Horseshoes, of which the following is a specification.

My invention relates to horseshoes which are provided with movable calks, and has for its object to render such horseshoes cheaper as regards first cost, easy of application and renewal, while avoiding as much. as possible injury to the hoof.

In describing the invention reference will be had to the accompanying drawings, in which Figure 1 is a plan of the shoe with improved calks; Fig. 2. a section through the shoe along line A B; Fig. 3, a front view of the shoe;

Fig. 4, a section along line O D ot' Fig. 1, and

Fig. 5 a. side view ot' a calk.

M v invention consists in a horseshoe lprovided with a socket having a groove which is arranged longitudinally iu the socket, at the ends thereof', and transversely at a point between its said longitudinal portions, in combination with a heel or toe valk provided with a shank having a pin which is received in said groove, as more fully hereinafter set forth.

Oonical holes d, e, andfare drilled into the shoe, anli the circumference of each ot' these holes is provided with a groove commencing at vthe lower face, with a longitudinal or rising portion, g, continuing with a semicircular or circumferential portion, h, and ending again in. alongitudinal or rising portion, ,which reaches to the upper face of the shoe. Into the conical holes d, e, and j' tit exactly the corresponding oalks, the conical upper part of which is provided with a pin,k, Fig. 5. This pin, which serves to secure the calk in its conical socket, is introduced into the groove from the lower (No model.)

face ot' the shoe, subsequently turned round with the pin until it arrives at the bottom of the guide or groove and introduced into the latter by striking the calk with'the hammer. The guides or grooves g ht' are clearly shown by Fig. 2. Compared with similar descriptions of calks, the present construction has the great advantage of preventing the calk from falling out ot' the socket.

For exchanging the calks it is suicient to drive the pin 7s down to the level of the guide h .by a stroke ofthe hammer on the upper end ot' the calk, after which the latter can be easily removed by hand. The calks may have any suitable shape; but in the winter it is advantageous to replace them by sharp-poin ted calks.

As will be seen from the drawings, the'parts ofthe horseshoe which surround the calkesockets are suitably strengthened. j

It is evident that the shape of' the groove and ot' the pin may be altered Without departing from the nature ot' my invention.

What I claim is- I A horseshoe provided with a socket having a groove which is arranged longitudinally in` the socket,at the endsthereof, and transversely at a point between its said longitudinal portions, in combination with a heel or toe calk FRIEDRICH ALRERTAUER.
